Would You Please Do Me A Favor?
A dentist, after completing work on a patient, came to him begging.
Dentist: Could you help me? Could you give out a few of your loudest, most painful screams?
Patient: Why? Docor, it wasn't all that bad this time.
Dentist: There are so many people in the waiting room right now, and I don't want to miss the four o'clock ball game.
